AUTOMOBILE snirrING-JACK.

To all whom t may concern:

Be it known that I, CHARLS W. OSH, a citizen of the United States, residing at San Francisco, in the county of San Francisco, State of California, have invented certain new and'useful Improvementsyin Automobile Shifting-Jacks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same.

This invention relates to new and useful improvements in jacks and has particular reference to jacks which are mounted for lifting and laterally moving objects.

The object of the present invention resides in the provision of a jack especially designed to lift automobiles and move them laterally.

The invention finds an especial application in moving to the side of a road automobiles which have become disabled.

A further object of the invention resides in the provision of means whereby the jack may be utilized to lift and laterally move automobiles which have sunk in the mud or sand.

The invention further contemplates the provision of a device of the above class which is eflicient in operation, readily manipulated and which possesses a simple structure so that it may be manufactured at a comparatively low cost.

With these and other objects in view, the invention resides in the novel combination, formation, and arrangement of parts to be more fully hereinafter described and illustrated in the accompanying drawings and particularly pointed out in the claim hereto appended.'

Reference is had to the accompanying drawings wherein similar characters of reference designate corresponding parts throughout the several views, and in which:

Figure 1 is a side elevational view of the improved device, Fig. 2 is a front elevational view thereof, Fig. 3 is a top plan view of the device the upper portion of the j ack proper being removed, Fig. 4 is a longitudinal sectional view taken on the line l-Jl of Fig. 2, Fig. 5 is a transverse sectional view taken on the line 5-5 of Fig. 1, and Fig. 6 is a detail sectional view showing the means foil lifting an automobile or otherobject from the mud, or from a low position, Fig. 7 is a Specification of Letters Patent.

Application filed September 22, 1913. Serial No. 791,141.

vided a jack A which is slidably mounted inr a track B. rIhe jack is generally of the usual construction comprising the casing 5 carrying means 6 for vertically moving the sliding jack bar L7 formed in its upperlend with the engaging head 8. The lower end y of this casing 5 is enlarged and provided with a horizontal groove 9 on each side thereof. The track B comprises a channelshaped member having its upper edges directed inwardly and slidably seating in the groove 9 to assist in holding the casing properly for sliding movement. The front end of the track member is provided with a wall 11 and the bottomy of the rear end of the track member is extended outwardly, as at 11.

The means for sliding the jack proper on the track member comprises a pair of feed screws 12 which are threaded in bores 13 in the lower end of the casing 5. These screws terminate adjacent the rear end of the track member and have their forward ends eX- tended through and rotatable in the wall 11, said ends being held with relation to the walls' by collars 1e on the screws inwardly of the said wall and collars 15 secured to the screws outwardly of the walls. FiXed to the ends of the screws outwardly of the wall are a pair of intermeshing gears 16 and the extremities of the screws are squared to receive a ratchet wrench. The screws are provided respectively with right and left hand threads and therefore when one of the screws is rotated by a ratchet wrench both screws will be actuated to move the jack proper upon the track member.

In operation, the device is placed under the automobile and the jack mechanism actuated to lift the same, a ratchet wrench 18 is then fitted on the squared end of the screw and the jack is moved to carry the automobile to one side.

It will be understood that there may be any number of these devices used, as one maybe placed adjacent each wheel or one may be placed under each axle of the car.

Then it is desired to lift an automobile which is'sunk in mud or sand or to lift and transport any object upon which a grip adjacent the ground must be obtained, the same may be accomplished by ya reduced rearward extension 17 at the-lower end of the sliding bar 7 which is slidable in a vertical slot 18 in the casing 5. In operation, the jack proper is moved until this eXtension is disposed outwardly of the track Inember and over the outward extension at the rear of the track member. The extension 17 is then inserted under the aXle or other object, the feed mechanism operated to lift the obJect and the feed screws then actuated to horizontally move the same. In this connection the automobile is moved forwardly or rearwardly.

From the foregoing it is observed that a very simple structure has been provided which will efficiently perform all of the functions normally required thereof.

The wrench`18 comprises a shank por* tion v19 carrying at one end the rotatable. head having squared sockets 21 at each end thereof for receiving the squared endsV of the shaft 12. The ratchet means for rotatf ing the head upon rocking movement of the Copies of this patent may be obtained for shank comprises a plurality of ratchet teeth 22 formed on the head and a spring-pressed pivoted pawl 22 engaging the ratchet teeth to prevent rotation of the head in one direction with relation to the shank.

What is claimed is:
